As well as the standard adult Xenomorph and Predator creatures, Sekeris also conceptualized new designs for the Queen and Facehugger forms of the Alien. However, the producers on Alien vs. Predator considered these new designs to be too far removed from the creatures seen in previous films, and as a result they were rejected. Other notable films Sekeris worked on include Blade II (2002), Terminator 3: Rise oft he Machines (2003), X-Men: The Last Stand (2006) and Star Trek Into Darkness (2013).
